Why is "no" not an acceptable answer to the question, "are you okay?"
The same thing goes for the answer "Oh, I'm all right," when someone asks "how are you doing?"
Why would you ask me a question like that for which you are expecting a specific answer and then be surprised when I didn't go along with your plan?
Next time just say, "Hey. Tell me that you're fine so that I can stop worrying about it."
It's all right. I understand.
